Check theair cleaner daily or before starting the engine.
Check for a buildup of dirt and debris around the air
cleaner system. Keep this area clean. Also check for
loose or damaged components. Replace all bent or
damaged air cleaner components.
Note: Operating the engine with loose or damaged air
cleaner components could allow unfiltered air
into the engine causing premature wear and
failure.
Paper Element Service
Replace the paper element at the intervals indicated in
the service schedule. See Figure 5-7 for the air cleaner
components.
1. Press the OFF button on the generator set
controller.
2. Disconnect the utility power to the generator set.

7. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent

5.5 Cooling System
The engine fan draws cooling air through the openings
in the sides and end near the battery. The alternator fan
draws cooling air through openings on the side walls of
the enclosure. The cooling air mixes with the engine
exhaust andis discharged atthe exhaust outlet. Seethe
service view in Section 1.9 for air intake and exhaust
locations. To prevent generator set damage caused by
overheating, keep the housing cooling inlets and outlets
clean and unobstructed at all times.
Note: Do not block thegenerator set coolingair inlets or
mount other equipment above them. Overheating
and severe generator damage may occur.
